Specification of Letters latent. Patefitgd June 27, 1922.

Original application filed May 13, 1920, Serial No. 381,043. Divided and this application filed February 23, 1921. Serial No. 347,118.

v T 0 all whom it may concern.

in Metal W indow Constructionsyof which the following is a full,clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates generally to metallic window construction and more particularly to that type of metallic window having a stationary sash or frame and a swinging sash or frame which performs the functions of a ventilator, the principal objects of our invention being to provide a relatively simple, strong, durable, and economical construction that is capable of being easily and cheaply produced and which, when properly closed, is weather and dust proof.

Our present application is a division of an application filed by Frank Mesker, Clarence E. Smith and Jacob Beuc on May 13, 1920, Serial No. 381,043, and relates particularly to the construction formi'ng'the hingeless j oint'between the ventilator frame and the window sash. By hingeless joint,

we mean a joint in which there is not present a hinge pintle or trunnion such as is usually employed in constructions of this kind. We form a swinging joint between the ventilator frame and the window sash, preferably by mutilating the inwardly extending flange of the T-shaped member of the window sash which forms one of the edges of the ventilator opening by notohing said flange and bending the tongue produced by the notching outwardly and downwardly flanges of said upright rails.

claimed, and illustrated in the accompanying drawings, in which Figure 1 is an elevational view of a metal window constructed in accordance with our 1nvent1on and looking at the out'erjslde thereof.

Figure 2 is a vertical section taken approximately on the line 22 of Figure 1.

Figure 3 is an enlarged detail section taken approximately on the line 3-3 of Figure 1 with parts broken away in order to more clearly illustrate the hinge connection between "the swinging ventilator section and parts of the window sash.

Figure 4 is a perspective view of a portion of one of the vertical rails of the window sash, the same being provided with a bearing for the swinging ventilator section.

Figure 5 is'a perspective view of one of the vertical rails of the swinging Ventilator section.

Figures 6 to 9, inclusive, are detail side elevational views of modified forms of swinging joints.

Figure 10 is a sectional view on line 10-- 10 of Figure 6.

Figure 11 is a sectional view on line 11- 11 of Figure 6.

In the drawings, 1 indicates the upright side rails of the sash, 2 the top rail, 3 the bottom rail, 4 the mullions or intermediate upright rails, and 5 the intermediatehorizontally disposed rails. These rails are preferably contructed of commercially rolled. bars T-shaped in section with their centrally disposed webs outwardly pre sented.

The ventilator frame comprisesa pair of upright side rails 13, a top rail 14:, a bottom rail 15, one or more upright intermediate rails or mullions such as 16, and one. or more intermediate transverse rails such as 17.

The upright side rails 13 of the ventilator frame are formed with a jog or bend 13 near their centers so that the lower portions 13 of said rails are offset with respect to the upper portions 13 and this arrangement provides abrupt shoulders 13 on the (See Figure bent portions 1 (see Figure 11) shed.

When the ventilator frame is properly positionedin its opening in the sash, the shoulders 13* on the upright side members 13 of the ventilator frame bear directly upon the rounded upper ends 4 of the inwardly presented flanges 45 and thus the ends et of said flanges constitute fulcrums or bearings upon which the ventilator frame is mounted for swinging movement.

Owing to the fact that the upper portions of the rails 13 are offset with respect to the lower portions, said upper portions will, when the ventilator is closed, lie immediately against the inner faces of the inwardly presented flanges i above the outwardly and the outwardly presented flanges of the lower portions 13 of said side rails 13 will bear directly against the outer faces of those portions of the flangesd which are below the shoulder 43. (See Figures 1, 2, 3, 10 and 11). Also when the ventilator is closed, the top rail 1d will lie directly against the inner face of the dependin flange of the intermediate transverse rail 0 that is disposed above the ventilator opening, and the depending flange of the bottom rail 15 bears directly against the outer face of that portion of the transverse rail 5 that is disposed below the ventilator opening.

In Figures 6 to 11, inclusive, we have shown different forms of means for maintaining the hinged connections between the ventilator frame and parts of the sash on which the frame swings, and which arrangements are 7 intended to counteract any tendency of the ventilator frame to become accidentally disengaged from its swinging position upon the sash frame.

In Figures 6, 10 and 11, the retaining means takes the form of one or more rivets 18 which are inserted through the flanges of the upright rails 13 and the heads of the rivets projecting from the undersides of the shoulders 18 so as to form depending lugs which retain said shoulders on the bear ing 4:.

The construction illustrated in Figure 7 includes a retaining lug or teat such as 18 thatis formed in the underside of the shoulder 18 in any suitable manner, either by being soldered or brazed thereto.

In the construction illustrated in Figure 8 the metal in the rear portion of the shoulder 18 is distorted by being punched or or vice versa.

pressed downwardly to form a short shoulder or retaining flange 18, and in the construction illustrated in Figure 9, a tongue or finger 18 is stamped or pressed from the web of rail 13 and bent upwardly against the underside of shoulder 18. These retaining lugs or flanges are easily formed and are effective in holding the swinging frame in proper position upon the bearings a, and particularly while the ventilator is swung open to a considerable angle.

Our improved construction provides for the mounting of the swinging ventilator without the necessity of extraneous fittings such as hinges, brackets, and the like, and the construction is such that the ventilator can be readily applied to the sash or removed therefrom and likewise it can be readily swung from closed to open position The members of the ventilator frame when closed lit snugly agaii'ist the adjacent parts of the sash and such an arrangement provides dust and weatherproof joints between the ventilator and sash frames.

Obviously minor changes in the details of construction may be made by those skilled in the art, without departing from the spirit of our invention, the scope of which is set forth in the appended claims.

e claim as our invention:

1. In metallic window construction, asash formed of metal rails and provided with an opening adapted to receive a swinging ventilator, the rails to the sides of the ventilator opening having inwardly presented flanges that are slotted to form horizontally disposed shoulders, and a ventilator frame positioned in the opening in said sash, said ventilator frame including flanged upright side members, the flanges of which are bent intermediate their ends to provide shoulders which are adapted to rest upon and cooperate with the shoulders on, the upright rails of the sash. 7

2.

3. In metal window construction, a sash formed of metal, rails and provided with an opening adapted to receive a swinging ventilator, the rails to the sides of the ventilator opening having inwardly presented flanges that are slotted horizontally, and portions of the flange immediately above the slots being bent outwardly, and a ventilator frame positioned in said opening and including numbers which are bent intermediate their ends to provide shoulders which bear upon the ends of the inwardly presented flanges of the rails to the sides of the ventilator opening immediately below the slots therein.

6. A metal window sash having a ventilator opening, an edge of which is formed by a flanged member, a swinging ventilator frame also having an edge formed of a flanged member, one of said members having a slot in its flange and the other of said members having a jog or bend in its flange forming a shoulder for cooperating with one edge of said slot to form a pivotal axis for the swinging frame.
